A GUI wizard tool is also included to assist the user to construct a command that will perform the desired task.

Each command-line tool is a thin wrapper around functionality in an object-oriented C++ class library. So, if you find one of the tools to be useful, you can also link its functionality into your code. The command-line tools may serve as demos for how to use the class library. Also, a collection of additional demo apps is included to exhibit some of the classes that are not exposed by the command-line tools.
